(a)Consider one object which has a temperature of 70°C in another object which has a temperature of 10°C. The two objects are placed next to each other in the particles in each object begin colliding. Will any of the collisions result in the transfer of energy from object to the object one? Explain. (b)Suppose that object one in object to have reached a thermal equilibrium. Do the particles of the two objects steel collide with each other? If so do any of the collisions result in the transfer of energy between the two objects? Explain.
